4-5. Placing the T-shirt on the Platen
CAUTION
Ensure there is adequate space left for safe working. The Platen moves forward while operating.
Do not handle the platen while printing. If your hand gets caught between the platen or the T-shirt
tray and the covers, it may be injured.
Do not move the Platen by hand.
The Printer may be mechanically and electrically damaged.
To get the optimum quality print result, you need to adjust the Platen height depending on the thickness of the
T-shirt.
<Note>
The clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm. If the
clearance is wider, the ink mist will spread inside the printer and the printing material, and may damage the
sensors inside. If you print with wider clearance (more than 2 mm) then check the inside of the printer and
keep it clean. Replace the Maintenance Parts by referring to "6-1. Replacing Consumables" and clean by
"6-1-6. Cleaning the inside of the printer and restart" and "6-1-7. Cleaning the Encoder Strip".
If Platen height is too low, the result may be poor quality (e.g. a straight line becomes double). Adjust it
properly by test moving the platen in with Platen Button on the Control Panel. When you have to lower the
Platen to avoid any material which is thicker i.e. hems the hems, use Uni-Directional print (see "7-2-4.
Changing the Print Direction"). You can set a print data as Uni-Directional by the Printer Driver. See "4-3-14.
Setting Print Direction as Uni-Directional".
The Platen height can be lower by 13 mm by replacing the Bush Platen Shaft with Platen Height Adjustment
Lever assembled and the Platen Positioning Plate to "Platen Lowering Set" (option). See "4-4-3. Lowering the
Platen height".
(1) If the Platen is not ejected, press the Platen Button to eject it.
(2) Loose the Platen Fix Lever and adjust the Platen Height to "A" position (leftmost) for T-shirt. Set it to the "C"
position when you print on a sweater or a towel. If the Platen height is too low, the print quality turns worse.
Keep the clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm.
<Note> Do not use force when you adjust the levers.
(3) Tighten the Platen Fixing Lever securely.
